| dc.description.abstract | Abstract This research aimed to check the construct validity of competency indicators of scientific literacy in junior secondary students. The steps for conducting the research included a sample of 392 persons, derived from stratified random sampling, from a population of 22,855. The instrument used in this research is a measurement tool with a reliability of 0.838. Statistical analysis includes confirmatory factor analysis, mean, standard deviation, and one-way analysis of variance. The study results found that scientific literacy indicators of junior secondary students had construct validity by taking into consideration Chi-square = 20.842, df = 17, p = 0.233 and X 2 / df = 1.226. which was less than 2, while RMSEA = 0.024, RMR = 0.07, which was near to 0, GFI = 0.987, AGFI = 0.972, CFI = 0.979. | |
